RGB vs. HEX — when to use which

HEX is shorter and more common in design tools, brand guidelines, and CSS. RGB is preferred when you need to dynamically compose colors in CSS (e.g. with CSS custom properties) or when working programmatically with color channels. Both produce identical colors in browsers.
